2x + y = 3 is the blue boundary line...the shading is below the line which means 2x + y is less than or equal to 3
y - x = 2 is the red boundary line... the shading is above the line which means
y - x is greater than or equal to 2
ANSWER: 2x + y is less than or equal to 3 and y - x is greater than or equal to 2
It’s A
Explanation / when you multiply 7 by -9 you get -63
In a geometric progression:
a, b, c, d...
The common ratio can be obtained using:
b/a = c/b = d/c
b/a = 112 / 64 = 1.75
c/b = 196 / 112 = 1.75
d/c = 343 / 196 = 1.75
The common ratio = 1.75
